ABSTRACT:
A cathode ray tube device has a neck, a funnel, a face panel, an inner conductive film disposed on an inner surface of the funnel, a first outer conductive film disposed on an outer surface of the funnel, and a deflection yoke. The inner conductive film and the first outer conductive film act as a capacitor. A second outer conductive film for electric field shielding is disposed on an outer surface of the funnel. The second conductive film is disposed between the deflection yoke and the first outer conductive film in such a way that the second outer conductive film is separated from the deflection yoke and is not covered by the deflection yoke.
